A Registered Receiver M-16 is worth a bunch of money because there are so few that are transferable to civilians (same with all transferable machine guns). This makes them excellent investments under basic supply & demand.Maybe I just missed something. . . . .
But,
Even after years as a Captain in the US Army Reserves, I don't see what the big deal is with full-auto or burst-fire weapons.
I can understand not letting nutcases or terrorists have something like twin truck-mounted .50 Cal BMG's.
But, what is the big difference between a M16 and an AR15, anyway ?
